which ones are adaptive immunity
1,2,3
which ones are innate immunity
4
an excessive immune response can be categorized as?
ACID
alergic, cytotoxic, immune complex, delayed
anaphylaxis results
decrease BP, airway obstruction, hypoxia
risk factors anaphylaxis
asthma
acute infection
patho of anaphylaxis
large amounts of chemical mediators are released from mast cells resulting in
vasodilation, edema in lungs
three criteria for diagnosing anaphylaxis
1 - acute, skin, mucas, respiratory or BP effected
2- two of: skin/music, response, gastintestional pain
3- rescued BP, known alergen
epinephrine effect
inc BP, RR, HR
vasoconstriciton
antihistamine effect
block mast cell activity
glucocorticoids. mech n effect
anti inflamm
slower action
intravenous fluid mech n effect
direct
Incase BP quick
myasthenia gravis
acquired autominnue deficit of ACH
fatigued
risk factors myasthenia
viral infection
patho myasthenia
mm cell death
